ok so my plan is to get a 4.5 rough country suspension lift with 31"s... now the question is.. do i for certain need an SYE and CV drive shaft? or is it ok to run without one? it myt be a stupid question but im new to this kind of stuff so please throw advice my way!

thanks guys!

 

Alot of ppl worry too much about this stuff, BUT if you have the cash get it done. I have the RC 4.5 and i dont have either but i plan on going bigger (as everyone always does) 4.5+ you'll end up needing the TC drop

 

maybe, maybe not...

your Jeep is newer, as a result you have the transfer case and drive shaft setup that are really prone to vibrations...

mine had vibes at only 3" of lift...

there are several things that can be done to combat this...

I will start from the cheapest and work my way up...

new rear u joints

t case drop

rear axle shims

YJ slip yoke swap

fixed yoke swap with front d shaft in rear

 

i would put the shims and the tcdrop in see what happens

 

Just did mine rusty's 4.5 with tc drop. No problems to report shocks are now broke in and rides great.

 

So i dont really need it? correct just to make sure i dont want to mess something up it is my daily driver so i dont wanna be left strainded because i didnt have the SYE and drive shaft..

 

i ran 6.5 lif tfor 5 years on ct drop with shims im a 89 but never had aproblem ever

 

Thanks man! ill have to try that where would you suggest gettin ct drop and shims?

 

where ever you buy the lift should carry what you need if they dont order you stuff some place else

 

ok thanks any other pointers? like i said i am new to this so any advice helps

 

Usually when you buy a lift like 4" and up they come with a TC drop, even if its only a 1" drop it helps,

 

maybe, maybe not... you will not know until you try it

 

HAHA that sounds like a great plan...

 

Hmmm.. I will have to double check the kit again to see if they come with it.

 

if not they are easy and cheap to make at home

all you need is some 1" thick steel rectangle or square tubing and drill some holes

you will also need some longer bolts... around 2" or so should work... they just need to be at least 1" longer than stock... grade 5 or better

here is a walk thru
